 throat of the receptacle is sometimes bare, 1 sometimes furnished with 

 a disk forming a laciniate frill. Within the valvate tetramerous

calyx are sometimes four petals, but they are often quite absent. In 

 Niebuhria? which belongs to tins genus, the receptacular tube is often 

 shorter, and the stipitate gynaeceum has two or three multiovulate pla- 

 centas. The fruit is ovoid and shorter than in Mcerua proper where it 

 is usually cylindroidal and torulose. Thus we find here the same 

 variations as in Capparis. We even find in certain species, for which 

 the genus Courbonia 8 has been proposed, that there are, as in some 

 Capers, only a few ovules, about two on either placenta, and that the 

 berry becomes ovoid or globular, with one seed or very few. Mcerua * 



1 This is the case in Streblocarpus (Akn., in 

 Ann. Sc. Nat., ser. 2, ii. 235; — Endl., Gen., n. 

 4997), which has four petals, and is distinguished 

 hy these characters as a section apart in the 

 genus Mania, from which it had been separated. 

 But in Pumarua the edge of the receptacle is 

 frilled.
